Any normal person in an every day job knows exactly what it is like to become tiresome and agitated but Iker Casillas, Spain's number one would probably never imagined it happening to him.
It has been a strange year for Madrid's saint, who has seen himself involved in several off-field spats and was dropped from the Madrid starting eleven for the first time in over a decade.
And it seems now, Casillas may be about to call time on his career with the club, much like Victor Valdes has at Barcelona.
Why? Well, again like Valdes over in Catalonia, Iker Casillas has never really had any competition for his place, he has played more times for Spain than anyone else but with a lack of drive and competition, could Casillas have now become complacent and tiresome of his role.
Casillas, as a keeper, has it all, we all know that, but at 31-year-old he should now be at the peak of his career, however under Jose Mourinho this season, things have become stail.
Reports of an ultimatum to club president Florentino Perez led by Casillas have only further exposed the dressing room tension at Madrid and to make matters worse, the number one has now been ruled out for 12 weeks with a broken hand.
His replacement, Diego Lopez, a former youth academy players is no slouch, he comes with a huge reputation, having performed at a high level for Villarreal in recent seasons.
His contract is set until 2017 and rightfully so, he will fight for the number one jersey but for Casillas, who has never had true competition, could this be the final nail the coffin so to speak.
One would certainly hope not, but Barcelona probably never through Valdes would leave the club he has served for his entire career. Whilst, under any other coach Mourinho would recover his hand injury and walk back into the starting eleven, this time he will have a new battle on his hands, something at the age of 31, he probably never expected to have.
